Based on best-selling author Jacqueline Susann's last novel, "Jacqueline Susann's Once Is Not Enough" (1975)' is a soapy tale of glitz, glamour and too much of both. A down-on-his-luck Hollywood producer will do anything to keep his spoiled 19-year-old daughter in the lifestyle she loves, even if it means marrying a wealthy lesbian. Starring Kirk Douglas, Alexis Smith, George Hamilton, Melina Mercouri and, in an Oscar-nominated turn, Brenda Vaccaro.
